Recompense's profile

:
The problem with those replays is not that Riot don't want us to see the replay: It is a technical problem.
In nearly every game you can't watch replays from earlier versions.
Replays aren't some kind of videos, they are basically scripted versions of a game.
And the scripted versions aren't the same in those two versions, therefore the result would be different - if f.e. Aatrox gets his damage trippled in a patch, the replay in the "new version" would show him crushing all his enemies - while in reality he was always destroyed.
Saying "the last few games can re replayed" would be the same as saying: "All replays from the old patch can be replayed."
It is technically really difficult and not just some switch to activate.

Yeah, this is what I tried to say with my argument to my idea.
In your words it looks as even less possible to be implemented.
Edit: thinking about how much more room will League need, despite work, to get this suggestion up and running. League already has a weight of 19-20 GB on my SSD

No you cannon replay it after new patch hits, in client or otherwise*
*Example: [Neace's tutorial on how to replay games of others (youtube)](https://www.youtube.com/watch?v=oEQpaPmbUp0)
Edit: I just used Neace's trick, to see if it will work, via putting last patch's replay.rofl file onto one special League executable and it broke my client, so I am waiting for it to automatically repair itself now
